|
The hormone interacts with the nerves at the base of the brain and directs signals to the target cells through the nervous system.
|
|
The hormone diffuses into target cells adjacent to the anterior pituitary gland, where the hormone is degraded.
|
|
The hormone is released into the bloodstream where it can be transported to all cells with the correct receptors.
|
|
The hormone moves through cytoplasmic connections between cells until it has reached all cells with the correct intracellular binding sites.

Detailed explanation-1: -A hydrophilic peptide hormone is produced in the anterior pituitary gland located at the base of the brain. The hormone targets specific cells in many parts of the body.
Detailed explanation-2: -Plant cells communicate with each other via narrow channels embedded across adjacent cell walls. These channels, called plasmodesmata, allow molecules to pass between cells, thereby enabling plants to grow normally and develop tissues and organs.
Detailed explanation-3: -Which of the following statements best describes a primary function of plasmodesmata? They allow the movement of molecules from one cell to another, enabling communication between cells.
Detailed explanation-4: -Which of the following will most likely result from a loss of p53 function? There are not enough nucleotides available to construct new DNA.
